Abstract
The present application aims to provide a thermal recording material which is low in safety concerns of endocrine disruptors, excellent in color development and light resistance, and excellent in heat resistance. The thermal recording material (1) has a configuration in which a thermal recording layer (3) is layered on a substrate (2). The thermal recording layer (3) contains a color developer, a non-phenol color former, and a non-phenol ultraviolet absorber. The non-phenol ultraviolet absorber contains an oxanilide ultraviolet absorber. The non-phenol color former preferably contains a compound represented by the following formula (1) and / or a compound represented by the following formula (2). (The definitions of the symbols in the following formulae (1) and (2) are as described in the specification).
